'ro ALL wH'oM 1T MAY coNcnRN:

Be it known that we, EDWARD A. MARSH and JARVIS P. KELLY, of Chicopee, in thc county of Hampden, and State of Massachusetts, have invented an Improvement in the Manufacture of Steel Pens; and we do hereby declare that the following, taken in connection with the drawings which accompany and form part of this speciication, is a Vdescription of our inventionisuilicient to enable those skilled in the art to practise it.

The invention relates to the manufacture of steel pens, or to that process in such manufacture which consists in cutting the blanks o r flats from the -metal' plates. j

The ordinary practice, after properly preparing the plate, is to cut or punch out these blanks by hand, and the object of this invention is to so construct and organize a mechanism that the blanks shall be successively and automatically cut from the plate, as it is intermittently fed to the action of a punch and die, theA invention consisting in the manner of keeping the plate in position during its feed or progressive movement, and in a mechanism for simultaneously throwing out of connection with a ratchet-wheel, through which the feed is produced, a train or series of pawls which operate upon the ratchet. The drawings represent a machine embodying my invention- A, showing a front elevation.

B, a side elevation; and

C, a rearelevation of the operative parts.

D is a horizontal section taken through the punch.

Upon a frame, a, is a standard, b, having housings for a driving-shaft, c.4 At the front end of this shaft is a crank, which, by means of a connecting-rod, d, imparts vertical reciprocating motion to a punch, e. On the tablefis a bed, g, in which is inserted a die, i, in the path of movement ofthe punch, the recess in the die corresponding in 'form to the form which the blank is to have, said blank being cut by the action of the punch in conjunction with this die. The plate of steell from which the blanks are to be cut is in the form of a long strip, having a width sufficient for cutting two pens in length, as seen at E, which represents a ,portion of the strip after blanks have been cut from part of it. Upon the rear end of the driving-shaft is an eccentric, which, through the medium of a connecting-rod, c', gives motion to a bent rocker-lever, 7c, which in turn is jointed to and imparts an oscillating movement to a ring, Z, bearing pawls m, which engage with and drive a ratchet-wheel, n. This ratchet is fixed upon one ond of a shaft, o, whose opposite end bears a pinion, p, engaging with ,the teeth of a rack, 9,'on Athe bottom of a long slide or carriage, r, sliding in the table or platform At one end of this carriage is a post or bearing, s, upon which is hung a clamp, t, having two jaws, between which the plate is pinched and held-while being fed to the action of the punch and die. I These jaws grasp the strip only at one end, the biting-lips being on a line in the direction of the movement of the carriage, and biting upon the strip lalong this centre line or just midway between its opposite edges. The carriage, being slid along so as to force the jaws up lto or nearly into contact with the die, the strip to be out sintrOduccd, one end being passed between the jaws, and so that they will bite upon the centre of the plate, which from lthese jaws passes along over the die la, (or between such die and a stripper-plate, 1a) under a roll, aand between guides w x, each having a lip under which the plate passes, one guide being made adjustable upon the platform laterally, while the other slides.

laterally with respect to the rst, so that they may be set to correspond to the width of the plate passing between them. Opposite the punch the edge or side not being cut passes between rolls y z. As the strip is to have blanks cut from each side, it is necessary that the feed should be very accurate at the .centre of the strip, in order to leave a web ljoining the parts left in the plate; and for this purpose the strip is held at one end, just at the centre, and is drawn along, by the feed mechanism, the strip being kept from swerving laterally by the edge guides; After one side is punched the strip is removed and vagain similarly introduced, but with its opposite side or edge in line with the punch and die, when, having been secured in the jaws, so as to cut'the first blank accurately with respect to 'the web left by those previously cut, the feed and guide mechanism will cause the remaining part of the plate to be similarly cut, as will be readily understood. In order that there shall always be a regular feed imparted to the plate, after each blow of the punch, three pawls are employed, so spaced with reference to the ratchet-teeth that one of the three will always act in such man- :1er as to cause a loss of feed at any time of not more than a third of the length oft, tooth- To trip these pawls,

for the purpose of stopping the feed and of sliding the carriage back, a ring, az, is placed inside of the pawlring Z; this ringo, carrying pins b2, which, bj slight rotary movement of the ring a2, acts upon two of the pawls and throws thcni out of engagement with the ratchet. The main pawl, which carries a handle, c2, has a in d2 on one side of its fulcrum which in entersthe rinrr a2. so that b movin the mein awl b hand to l) v P a y g P y 1 throw it from the ratchet, the ring a2 is turned.` bythe pin d2, causing the pins b2 to simultaneousl)T act upon the other pmvls, thus disengaging all'three of `the pawls and allowing the carriage r to be slid forward or back as circumstances may require.

We claim, in Ycombination Withthe die, reciprocating punch, stripper, and carriage, the jaws t, when arranged to clamp or grasp the plate at the centre line thereof, and draw it progressively and intermittently to the action of the punch, substantially as set forth. Wealso claim, in combination, the subjects of the rst claim, the guides w and x, ami guide-rolls y andiz, arranged to operate substantially as set forth.

We also Claim the arrangement of mechanism for .tripping or disengaging the series of ratchet-pawls, suhstantially as described.

JARVIS P. KELLY.
